In addition to perks & discounts that apply when you fly with them, these programs also offer great discounts on rental cars when you rent with a car rental partner agency. The best part is that you can can signup for free and get the discount even if you're not flying with that airline.

To make it easier to signup, we've added a free signup button to coupons available only to members of these programs. If you come across a great discount, book the rental and then signup for free to ensure you don't run into any surprises at the rental counter. Oh, and by the way, you can also stack these discounts with other coupons to make a good deal even better!

Over the next few weeks, we plan to add a number of new Frequent Flyer programs that offer car rental discounts. We're also working to introduce Hotel Rewards programs to ensure that you don't miss out on any discounts. Stay tuned.

If you have a favorite, let us know and we'll try & get it to it first.
